[0021] The present invention will be further described below with reference to the accompanying drawings and implementation examples.

[0022] Reference Figure 1-5A foamed cement composite panel for roofing comprises a foamed cement composite panel 1 suitable for roofing, a plurality of mounting holes 2 being opened on the side of the foamed cement composite panel 1, a connecting assembly 4 being arranged inside the mounting hole 2; the connecting assembly 4 comprises a connecting tube 41, a grouting pipe 42 being connected and installed on the side wall of the connecting tube 41, sealing slides 45 being slidably installed at the ports on both sides of the connecting tube 41, a plurality of round steels 46 being slidably passed between the two sealing slides 45, a plurality of hoops 47 being fixedly connected to the inner side of the round steel 46, a plurality of anchor strips 49 being installed on the outer side of the sealing slide 45, external threads 43 being arranged on both sides of the grouting pipe 42, and abutment rings 44 being screwed on the external threads 43.

[0023] Through the above-mentioned setting, the two abutment rings 44 screwed on the external thread 43 here abut against the outside of the mounting hole 2 during installation, and then by adjusting the distance between the two abutment rings 44, it is equivalent to controlling the distance between the two foamed cement composite panels 1. This setting helps to accurately control the width of the construction joint reserved when the foamed cement composite panels 1 are connected, which facilitates unified waterproofing treatment in the later stage and ensures the waterproof effect after waterproofing construction.

[0024] In this embodiment, the anchor bar 49 is a high-toughness steel bar.

[0025] Through the above-mentioned arrangement, the anchor bar 49 is a high-toughness steel bar. When the sealing slide 45 is inside the connecting tube 41, the side anchor bar 49 is restricted by the inner wall of the connecting tube 41, and the anchor bar 49 abuts against the inner wall of the connecting tube 41. When the sealing slide 45 subsequently slides out of the inner side of the connecting tube 41, the anchor bar 49 is expanded and restored to the outside under the action of the toughness of its material itself. This action can be used to expand and anchor to the inside of the inner anchoring hole 3.

[0026] In this embodiment, nuts 48 are screwed onto both ends of the round steel 46 .

[0027] The nut 48 is set in the above manner to limit the limiting effect of the sealing slide 45, preventing the sealing slide 45 from sliding out of the end of the round steel 46, thereby resulting in no connection between the anchor strip 49 on the side of the sealing slide 45 and the round steel 46.

[0028] In this embodiment, the outer diameter of the connecting tube 41 matches the inner diameter of the mounting hole 2 .

[0029] Through the above arrangement, when connecting and installing the foamed cement composite board 1 , the connecting tube 41 can be inserted into the inner side of the installation hole 2 .

[0030] In this embodiment, an inner anchoring hole 3 is opened inside the mounting hole 2 , and the inner diameter of the inner anchoring hole 3 is larger than that of the mounting hole 2 .

[0031] By the arrangement in the above manner, the inner anchoring hole 3 is convenient for interacting with the anchor bar 49 in the connecting assembly 4 to form a snap-fitting effect.

[0032] In this embodiment, the connecting tube 41, the grouting pipe 42 and the sealing slide plate 45 are all made of stainless steel.

[0033] Through the above-mentioned arrangement, the connecting tube 41, the grouting pipe 42 and the sealing slide 45 are all made of stainless steel, so that the connecting tube 41, the grouting pipe 42 and the sealing slide 45 have high structural strength and strong corrosion resistance.

[0034] In this embodiment, a plurality of round steel bars 46 are distributed at equal distances along the outer circumference of the hoop 47 .

[0035] By the arrangement in the above manner, the hoop 47 connects the plurality of round steels 46 into an integral skeleton, and the hoop 47 provides the shear resistance of the entire skeleton.

[0036] The working principle of the foamed cement composite board for roofing provided by the utility model is as follows:

[0037] When in use, the construction joint width of the foamed cement composite board 1 is determined in advance according to the construction process requirements, and the distance between the outer sides of the two abutment rings 44 screwed on the outer side of the connecting tube 41 is adjusted to match the specific width of the construction joint. Subsequently, one end of the connecting tube 41 is inserted into the inner side of the mounting hole 2 of the foamed cement composite board 1, and the mounting holes 2 of the intersection edges of the foamed cement composite board 1 are all inserted into the connecting tube 41. Subsequently, the mounting hole 2 of the other foamed cement composite board 1 to be assembled is aligned with the other end of the connecting tube 41, and it is slid to the outer side of the abutment ring 44. At this time, the distance between the two abutment rings 44 is the construction joint width. After the splicing work of all the panels is completed, unified grouting work is carried out later, and the cement mortar is introduced into the grouting pipe 42 through the grouting equipment, and the cement mortar can be The grouting pipe 42 enters the inner side of the connecting tube 41, and under the action of high pressure, pushes the sealing slide plate 45 on the inner side of the connecting tube 41 to both sides, so that the anchor strip 49 pressed between the side edge of the sealing slide plate 45 and the inner side of the connecting tube 41 expands outward, and then the anchor strip 49 stretches and is connected to the inner side of the inner anchor hole 3 on the inner side of the mounting hole 2. Subsequently, cement mortar is injected from the inner side of the connecting tube 41 to the inner sides of the mounting holes 2 and the inner anchor holes 3 on both sides. After drying, the cement mortar and the round steel 46, hoop 47 and anchor strips 49 riveted at both ends on the inner side of the connecting tube 41 form a steel-concrete connection body, which has high connection strength, and the connection skeleton is inside, with high corrosion resistance, which comprehensively strengthens the installation connection strength of the foamed cement composite board 1. Subsequently, the waterproof mortar is uniformly smoothed with the reserved construction joints to complete the waterproofing work.

[0038] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
